This week on The Colosseum, we cover the biggest stories in health, fitness, wellness, and human performance.
Your wearable is becoming a medical device. WHOOP just partnered with HealthEx to pull your actual electronic health records into the app — so diagnoses, medications, and procedures sit alongside your recovery, strain, and sleep, powered by WHOOP AI and "My Memory." Oura is heading the same direction, quietly turning the ring into a virtual doctor's office with cognitive testing and in-app telehealth. We dig into what this clinical era of wearables really means: the accuracy-vs-trends debate (and what the Apple Heart Study and validation research actually show), the privacy tradeoffs, and the thornier question of AI predicting — and even prescribing — your medication. Plus a new meta-analysis in the Journal of the American Heart Association finding wearables meaningfully boost activity in people with heart disease, and a head-to-head of Apple Watch vs. Whoop vs. Oura vs. Fitbit.
From there we get into the explosion of hybrid fitness: Nike-backed ONE LDN raising £2.5M to scale its HYROX-style training club, and what the rise of community-driven "all-in-one" gyms means for the industry. We break down Marten Van Riel going a perfect 6-for-6 in Ironman 70.3 with a course-record win at Elsinore, the contrast between data-driven Norwegian training and South Africa's deep ultra-running culture, and how HYROX has done something we've never seen before — spawned an entire category of shoes built from the ground up (Puma, Adidas, On, Brooks).
What is The Colosseum | Health & Performance?
The Colosseum is a weekly show built on a simple idea: modern science has answered a lot of questions about how to train, eat, recover, and live well — and most people are still left guessing.
Each episode, hosts Tyler and Jayden break down the latest news across health, wellness, and fitness. Exercise science. Endurance sports. Health tech. Performance nutrition. Recovery and longevity. It's the kind of honest, curious conversation you'd have with a friend who reads the research so you don't have to.
Expect deep dives on science, research, and training for IRONMAN, HYROX, and ultra-endurance events. Conversations with or about athletes, coaches, founders, and researchers pushing the field forward. And honest conversations about the wellness trends shaping how people train, eat, and recover.
New episodes weekly. Part of The Colosseum — a modern health movement.
